Researches on Nutrition in Cultivation of Chinese Fir

A series ofresearches on the nutrition problems in the cultivation of Chinese fir seedlings and plantations, which are mainly focus on the problems of serious land degradation in Chinese fir plantations in contradiction with the rapid development of the plantations in China, were summarized. Twelve years was taken and more than 30 pieces of research papers were published for the researches, which refers to the problems of growth effect, physiological effect, vegetation variation, biomass accumulation, nutrition dynamic, accumulation and distribution

Twelve years was taken and more than 30 pieces of research papers were published for the researches, which refers to the problems of growth effect, physiological effect, vegetation variation, biomass accumulation, nutrition dynamic, accumulation and distribution of Chinese fir seedlings and plantations under different nutrition conditions. The principle of nutrition equilibrium was used for the first time in the nutrient diagnosis offorest tree in China, and the techniques and target system of nutrient diagnosis which are suitable to seedling as well as plantations of Chinese fir were established according to the principle.
